#2 Ak-47
Ak-47 is arguably the most popular rifle in the world. It is known for its accuracy and efficiency. The AK-47 is an iconic assault rifle, popular among revolutionaries and known for its rugged, reliable design. It is based on a gas recoil system. But today, we are going to use Ak-47 in a very different way.
We are going to get some Physic lessons thanks to Ak-47. We know how they work with your basic point and click interface but we rarely get to see them work underwater. What would even happen if one was, for example, fired underwater? I know I've made you interested now. To check out what happens with the bullet underwater, look for the video on the next page!!!

#1 The Video
So here we are about to show you what happens when an Ak-47 rifle is fired underwater. Underwater, the bullet travels only about 5 to 6 feet (in the air, it can travel some 1,300 feet). But it's not a surprise as water is much more denser than the air. But this isn't the real point.
The real science clocks in at the 6-minute mark, in an explanation of how bubbles work underwater and the way pressure from the bullet turns water to vapor before the round has even left the barrel. So without wasting more time, check out the video and let us know about your views.
